The length() method of a String object in Java provides the precise count of characters contained within the string. It accurately represents the number of Unicode code units present in the string, thus capturing the complete textual content of the string. Syntax: public int length() There is ...
Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations ...
